I guarantee you the power plant is way more efficient than a billion little gas engines.
@Sluggernot, yeah but batteries are also a large amount of waste to make and dispose of
@Guy Fawkes, I've heard that the locations they are made and disposed of are wastelands.
@Sluggernot, there’s a lot of emission regulations for coal burners, but even more are powered by nuclear plants, which is statistically the most efficient form of energy with the least amount of bad waste
@Guy Fawkes, ((panik))
@Guy Fawkes, batteries do generate a lot of waste, but battery production produces less carbon than driving a gas car for 15k miles/year for a few years (so batteries produce less carbon in the long run)
@daweim0, idk much about the different kinds of emissions tbh i just know that the amount of emissions that go into obtaining and processing raw material into a battery is generally considered to be equal to our current emissions standards
and as a disclaimer this isn't something I keep up to date with much, this is info from the back of my mind that could've been made outdated by now. and I do look forward to a day when green energy is an accessible recourse for the world
@Guy Fawkes, yeah battery production isn't great but last I saw it's the lesser of two evils assume you drive the average amount
@Sluggernot, you lose power in converting energy. If electric cars aren't supported by green energy, they are worse than gasoline
@KingofFunnypics, batteries are like 95% efficient when converting energy. Way more efficient than hydrogen fuel cells. Electrical power plants are way more efficient than gas engines due to size and their ability to capture more heat instead of losing it as waste. Even electric vehicles charged by coal plants are greener than running on straight gasoline, and that will only improve as coal is phased out over the next few years. And finally, you can also recycle batteries into new batteries by reclaiming the material inside them, and as that ramps up, waste in production will drop.
Give me some solar panels!
Nuclear power gang ☢
@fudsterly, only France understands us feels bad
They also use rare earth metals. The mining of which is devastating to the local environment.
@CocoasBro, batteries don't use rare earth metals, and each new generation uses less Cobalt, which is toxic. Rare earth metals are only used in permanent magnets for the electrical motors, and even those are optional, like in Teslas.
@sams2er, not according to google. Google says that rare earth metals are widely seen as the most efficient way to power electric vehicles.
@CocoasBro, Where on Google? All of the Lithium Ion battery chemistries I looked up have zero rare earth metals in them. Tesla currently uses Nickel-Cobalt-Aluminum batteries, and most other companies are using Nickel-Manganese-Cobalt batteries. None of those contain rare earth elements, which are used to make the magnets in motors that drive the wheels. Even in motors though, it is possible to avoid them to save money at the cost of some efficiency. In fact, all catalytic converters use a bit of cerium dusting as well, so it isn't like we aren't already extracting tons of rare earth metals. All upped EV production will do is divert existing extraction to new markets, while still cutting out majorly destructive fossil fuel extraction.
@sams2er, nevermind google was being dumb. I googled "do electric cars use rare earth metals" and the answer came up as yes. But upon closer inspection it was referring to electric magnets... not electric cars for some reason.
@sams2er, ahh but electric magnets are a key components in electric motors.
@CocoasBro, So does damn near everything, including gas cars in the catalytic converter as well as in refining process to make gasoline. The awful fact of modern mining do need to be addressed, but it’s not really an electric car issue it’s a more general one.
We can find other ways to generate electricity, we don’t use the ones we have enough and that’s a different problem, but we don’t necessarily need burn things to power electric cars. We do need to burn things to power a gas engine, by definition.
I’m surprised no one has started complaining about the Amish horses farting....
